Active clinical trials for "Communicable Diseases"

The purpose of this study is to evaluate the efficacy, tolerability, and safety of BEZ235 alone and in combination with RAD001 to support further development to reduce the incidence of respiratory tract infections (RTIs) in elderly subjects.

Phase IV prospective study measuring the immunogenicity (neutralizing antibody titles against each HPV vaccine genotype) of the 9-valent vaccine against HPV (Gardasil9®Merck) in HIV-positive women aged 15-40 years with fully suppressed HIV viremia on combined antiretroviral therapy. After a first open phase evaluating tolerability of Gardasil9 (from June 2018 to December 2018), an amendment was introduced to randomize women between two different doses schedules: in the first schedule (ARM A), women will receive 2 doses at time 0 and 6 months and a third dose between 18-48 months if their antibody levels are insufficient; the second schedule (ARM B) will be 3 doses at 0, 2 and 6 months. Primary outcome is the non-inferiority of the rate of seroconversion against each HPV vaccine genotypes in women seronegative at baseline after either 2 or 3 doses of vaccination (month 7). Secondary outcomes are rate of seroconversion after 3 doses if they have received a third dose, completion of vaccine schedule, vaccine safety, antibody titles, and induction of cellular immunity against HPV contained in the vaccine, incidence of cervical HPV infection and incidence of abnormal cytology after vaccination. The safety of the vaccination (local or systemic reaction and impact on HIV viral control and immunodeficiency level) will be assessed. The cellular immune response will be assessed in a subgroup of patients.

The central aim of this trial is to investigate the safety and tolerability of Phage Cocktail-SPK as an adjunct to standard therapy for the prevention and treatment of burns susceptible to infection/or infected by S. aureus, P. aeruginosa, or K. pneumoniae species. It is hypothesized that no adverse events, clinical abnormalities, or changes in laboratory tests results related to the application of Phage Cocktail SPK Spray will be observed.

This is a Phase 3, double-blinded, randomised placebo-controlled, multi-centred trial evaluating the efficacy of the four-component meningococcal B vaccine, 4CMenB (Bexsero®), in the prevention of Neisseria gonorrhoeae infection.The targeted population is 18-50 years-old men (cis and trans), trans women and non-binary people who have sex with men (hereafter referred to as Gay Bisexual Men+ [GBM+], either HIV-negative and taking pre-exposure prophylaxis [PrEP], or HIV-positive with undetectable viral load <200copies/ml and a cluster of differentiation 4 [CD4] count >350 cells/cmm) who have high N. gonorrhoeae incidence and are recommended by Australian guidelines to have regular, comprehensive sexual health screening. 730 participants will be enrolled and randomised 1:1 and stratified by clinical sites to receive two doses of 4CMenB vaccine or a matching placebo at 0 and 3 months by intramuscular injection. Recruitment is for 12 months and all participants will be follow-up 3-monthly for a period of 2 years. The trial aims to evaluate the efficacy of 4CMenB in the prevention of N. gonorrhoeae infection.

Introduction. Some issues remain to be elucidated about SARS-CoV-2 infection to plan prevention interventions based on scientific evidence, such as the actual prevalence of infection including subclinical and seroconverted cases, the reasons for the different spread and severity of the infection in different subjects and geographical areas as well as the impact of the COVID-19 crisis on the health of healthcare professionals and in the general population. The aims of this project are: (i) to estimate and compare the real prevalence of the SARS-CoV-2 infection and seroconversion in two populations at high or low risk of infection,in Lombardia region and Molise region, respectively; focusing on subgroups at higher risk such as healthcare workers (HCWs); (ii) to estimate the incidence of burnout and post-traumatic stress disorder in HCWs; (iii) to identify factors associated with SARS-CoV-2 infection positivity and to follow up its mid-term effects on health. Methods. Participants will be randomly selected from the general population of both territories and from the HCWs list of the two healthcare facilities involved. SARS-CoV-2 IgG and IgM blood levels will be measured and anamnestic data will be collected through computerized tools. Prevalence of currently or previously infected subjects and their disease status and severity will be estimated and the association with potential risk factors will be analyzed through multivariable regression analyses. Expected results. The study will identify the burden of the infection in the general and HCWs populations. It will also identify the determinants of differences in the spread and severity of the infection, to hypothesize new preventive or therapeutic interventions. This study will provide a basis for monitoring the progress of the infection and its medium-term health consequences, Finally it will allow planning future studies, through analyses in biological samples which will be collected in dedicated biobanks.

This cohort study aims to describe the adverse events related to the use of bacteriophages to treat serious infections, data from the literature being almost non-existent on this subject.

Among the hemodialysis units, the global incidence of HCV infection ranges from 1.2% to 2.9%. Data regarding the long-term risk of reinfection among hemodialysis patients achieving SVR are limited. To our best knowledge, only one study assessed the long-term negativity of serum HCV RNA in hemodialysis patients who achieved SVR after IFN-based therapies. With a median follow-up of 48 months following SVR, the life-time cumulative survival for HCV RNA negativity was 86% among the 121 participants who were on maintenance dialysis. Furthermore, the life-time cumulative survival for HCV RNA negativity was 95% among the 45 participants who underwent renal transplantation from HCV-negative donors. Because the literatures regarding the long-term follow-up of viral outcome, the patient numbers to be recruited are still limited, and all studies are focused on IFN-based treatment, we aim to assess the long-term risk of HCV reinfection in hemodialysis patients attaining SVR by IFN-based or IFN-free therapies.

Dengue fever, an arbovirus transmitted by the Aedes mosquito, is a public health problem in all tropical and subtropical regions of the world. There is currently no antiviral treatment and vector control has shown its limits. The 2018 European marketing authorization of the tetravalent chimeric yellow fever / dengue vaccine (Dengvaxia®) is a major step forward in the fight against the disease. Dengvaxia® is indicated for the prevention of dengue due to serotypes DENV 1-4 in subjects aged 9 to 45 years with a history of infection with the dengue virus and living in endemic areas (seroprevalence of at least 70% in the target population). Dengue seroprevalence data in the French Caribbean territories of Martinique and Guadeloupe dates back to 2011 and concerns only adult blood donors aged 18 to 70 years. To date, no data exists for individuals aged 9 to 17 years in the region. In order to implement an optimal vaccine introduction strategy for these territories, the main aim of the DengueSEA study is to estimate the seroprevalence of the Dengue viruses (DENV 1-4) in 9-17 year olds giving a blood sample as part of care in hospital departments of the French Caribbean islands of Martinique and Guadeloupe.

Urinary tract infections (UTI) represent one of the most common morbidities in individuals with spinal cord injury (SCI) and reason for re-hospitalization. The consequences of recurrent UTI are a decrease in quality of life and considerable health costs. Immunomodulation therapy with UroVaxom is a very promising method for the prevention of UTI, however data in individuals with SCI are very limited. The primary objective of this pilot study is to evaluate the feasibility (recruitment rate, patient attrition, compliance, assessment procedures etc.) of a main trial. A secondary objective is to collect data for an informed sample size calculation. Furthermore, the clinical and biological changes after immunomodulation therapy will be investigated. This is a randomized, placebo-controlled, mono-centric pilot study investigating the feasibility of a main trial regarding the effectiveness of immunomodulation with UroVaxom in the prevention of UTI and the effect on the immune system in individuals with acute SCI during primary rehabilitation. There will be two parallel groups of 12 participants each. Group allocation will be based on a block-randomization stratified according to sex. Study participants and outcome assessors will be blinded to the group allocation. The nursing staff will be unblinded and will administer the treatment and the placebo. Study participants will either receive Uro-Vaxom (one tablet / day) or an off-the-shelf placebo for 90 days. After termination of the treatment, the study participants will be followed for 12 months. Blood and urine samples will be taken before and 90 days, 6 months and 12 months after treatment start.

The primary objective of the study is to determine whether dietary intervention to increase fiber and decrease fat reduces C. difficile infection recurrence in a cohort of oncology patients.
